VR-Training Project

Outline

Overview of the VR Project

VR-Training: Adapting Virtual Reality Training Applications by Dynamically Adjusting Visual Aspects

Motivation:
- Static training doesn’t fit everyone: Too easy → boredom, Too hard → anxiety
- Adaptive VR training balances difficulty to improve outcomes.

Scenario:
- Users move and place parcels in a VR warehouse using controllers.
- Visual cues: dynamic lighting and color guidance.

Adaptive Features:
- Tracks user behavior (head movement) and performance (time, errors).
- Adjusts lighting, object colors, etc., after each training round.

Terminology

Stress indicators:

• Perceived cognitive load (1 to 6 with 1 very low and 6 very high)
• Perceived physical load (1 to 6 with 1 very low and 6 very high)

Physiological Measurement Data (PMD)

• Heart measurements: Heart rate (HR), SDNN, RMSSD
• Skin conductance response (SCR) measurements: Skin conductance level (SCL), SCR frequency, SCR amplitude, SCR rising time
• Eye tracking measurements: Blink rate per minute, Saccade amplitude, Saccade velocity
